Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden, and it does substantial work: it declares this is a read operation ('Read first'), clarifies nothing is purchased or paid, no quote is guaranteed, and it is free. That directly addresses the key behavioral risk (an agent or user mistaking this for a commercial commitment). It omits any mention of auth needs or invocation constraints, keeping it short of a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The imperative 'Read first' is front-loaded and immediately actionable, followed by tightly packed sentences covering semantics, guarantees, and return content. It is efficient, though it partially restates the title's 'not a purchase, not a guaranteed quote' phrasing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description must convey what comes back, and it does list the payload (who receives the details, the consent wording, how the person confirms). For a zero-param informational tool this is sufficiently complete; only the relationship to enquiry_fields is left unstated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, and the schema is empty, so there are no parameter semantics to explain. Baseline 4 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: it describes/explains what submit_enquiry does (the enquiry process on Web design Poole). It names the sibling submit_enquiry explicitly and contrasts it ('nothing is bought, ordered or paid'), so an agent can tell this informational tool apart from the action tool. It does not, however, distinguish itself from the other sibling enquiry_fields.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Read first' gives an ordering cue relative to submit_enquiry, implying you consult this before submitting. Beyond that there is no explicit when-to-use vs enquiry_fields, and no stated exclusions or prerequisites. Usage is implied rather than spelled out.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
